A plurality of Nb rods are arranged in a cannister and the gaps filled with Cu 15 wt. per cent Sn powder. The cannister is evacuated, sealed, and extruded and may be subjected to rolling, drawing and swaging steps to metallurgically bond the materials together, annealing steps being included if desired. The conductor is finally heated to diffuse the Sn into the Nb to form Nb 3 Sn filaments  embedded in a Cu matrix. The conductor may be formed into a ribbon, twisted, or wound into a coil before heating to react the components. The Nb rods may be replaced by ribbons. In an alternative embodiment a billet of Cu-Sn is provided with bores which are filled with Nb rods or powder. The component which diffuses out of the matrix may also be selected to produce the compounds Nb 3 Al, Nb 3 Ga, and Al 0À5 Nb 3 Sn 0À5 , and the matrix itself may be of Ag, Al, Ni, Fe or Au.

Abstract: 1387920 Butadiene-styrene copolymerization V P SHATALOV Y M ROZINOER G M SINAISKY and M V BULGAKOVA 27 Sept 1972 [27 Sept 1971] 44585/72 Heading C3P Copolymers are prepared by simultaneously passing a mixture of styrene and butadiene to a reaction zone, the polymerization being carried out in the presence of a polymeric organodilithium compound, e.g. polybutadienedilithium, suitably in an organic medium. During the reaction the monomer mixture is added to the polymerization vessel at a rate at least as great as the rate of polymerization, and preferably 5-10% greater. The less reactive monomer, styrene, therefore builds up in the reaction mixture so that it forms an increasing proportion of the polymer towards the chain ends, and forms terminal homopolymer blocks after cessation of the addition of monomers and reaction of all the butadiene. The reaction may be carried out continuously in two autoclaves, monomers and initiator being continuously added to the first while the product, at 95-98% conversion, is drawn off into the second to complete its reaction.
